TIL'IING-SASH WINDOW.

Application filed April as,

My present invention relates to improvements in tilting sash windows, mobject being to provide a window of t is type which shall be thoroughlypractical in all respects to build, install and operate, and which willhave the hereinafter set forth other advantages.

In the drawings, which show the embodiment I at present prefer of myimprovements, Fi 1 is an elevational view of a tilting sas windowconstruction within my invention as seen from the inside, i. e. as iffrom within the building, the two sash being shown shut or closed; Fig.2 is the same except thatv the'view is from the outside of the building;Fig. 3 is a vertical sectional view, partly in elevation, on a largerscale through the same, the building stone-work at the top and bottom ofthe window bein also shown in vertical section, said figure eingeconomized as to height at the two places indicated by the broken lines,and the sash being shown shut; Fig. 4 is a horizontal and sectionalview, partly in plan, on the line 4-4 in Fig. 3, the stone-work of thebuilding at the sides of the. window being also shown in horizontalsection, said drawing being economized as to width at the two placesin-' dicated by the broken lines; Fig. 5 is a View" like Fig. 4 exceptthat it is on the line 5--5 in Fig. 3, namely, is on a horizontalsection through part of the lower sash and through one side only of thewindow frame; Fig. 6 is like part of the right side of Fig. 4except'that it shows certain removable panels detached; Fig. 7 is averticalsection; partly in elevation, on the line 77 in Fig. 4; Fig. 8is like Fig. 3 except that the sash are both shown tilted inwardly intoa horizontal position as for cleaning them; Figs. 9 and 10 arehorizontal sectional views, partly in plan, respectively on the lines9-9 and 10-10 in Fig. 8; Fig. 11 is a vertical sectional view, partly inelevation, on the line 11-11 in Fig. 4 looking in the direction of thearrows; Figs. 12 and 13 are broken away views in elevation of theaforesaid panels;

Fig. 14 is a vertical sectional, partly elevational, view through one ofthe sash weight compartments on the line 14-14 in Fig. 11 looking in thedirection of the arrows; Figs. 15 to 20 inclusive are views similar toFig. 8 on a smaller scale, showing some further manipulations andrelative positions of the sash possible with my construction.

I will now describe my improvements by 1928. Serial No. 635,250.

way of theparti'cularly preferred embodiment thereof shown in thedrawings but without limiting myself thereto except as may be requiredby the annexed claims properly construed.

A, B and C designate respectively the top, bottom and sides of the stoneor other buildng construction within which my window 1s shown mounted;

The drawings are intended to 'show a sheet metal fireproof constructionof the sash, wlndow frame, etc., but I do not limit myself to thesematerials.

1 and 2 respectively are the upper and lower sash. The sides of thewindow frame severally comprise a sash weight compartment 3, togetherwith a side section 4. These are united at the top by the headers 5 andat the bottom by the inner and outer sills 6 and 7.

The side of each sash weight compartment 3 adjacent the sash is made upof three panels, 3*, 3 3 (Figs. 8, 4, 6 and 11, etc), the first being afixed panel and the others being detachable at will to et at theinterior of'the compartment. gaid panels 3 and 3 are shown detached inFigs. 12 and 13. The panel 3 is attached at the top by screws to abracket 8 secured to the underside of the top of the sashwelghtcompartment; and at the bottom is attached by screws to a crosspiece 9 secured to the back of the panel 3 as best shown inFigs. 3 and11. Panel 3 is attached by screws at the top to a bracket 10 secured tothe underside of the top of the sash weight compartment and at thebottom by screws to another bracket 11 secured to the bottom of saidcompartment (Figs. 3, 11 and 14).

Said panels 3, 3*, 3 are laterally spaced when in position and areshaped at their side edges to provide two'guides located in each side ofthe window frame, namely, an inner guide 14 and an outer guide 15 (Figs.8, 11 and 15 to 20 inclusive, etc.).

In the description and claims, the expres sions inner and outer meantowards or shown at 14 (Fig. 11, etc.), and thence terminate each in ashort vertical downwardly extending portion 14 located directly underthe adjacent outer guide 15, but without communicating therewith. v

The sash 1 and 2 have respectively pins at the top and bottom projectingfrom their sides, the bottom pins being designated 15 and the top pins17, the latter being the free ends of rods, designated by the samenumeral, supported for free endwise movement in the upper rail of thesash, the inner ends of said rods being bent at right angles to projectloosely into holes in a disk 18 (Figs. 4 and 7) fixed on the stem 19rotatably supported in suitable bearings in said rail, said stem havingan integral external head 20 on the inner side of the rail for operatingsaid stem by partially rotating it and said disk to simultaneouslyretract the projecting free nds of the rods 17 against the 0 position ofthe springs 21 which normal y impel them outwardly to the extentindicated in said Figs. 4 and 7 until stopped by the collars 22 on saidrods. The. holes 23 in the ends of the head or handle 20 are adapted tobe engaged by the hook on a window pole for retracting the aforesaidrods and pins '17, particularly of the upper sash which willordinarily'be out of reach for direct manual operation.

The lower and permanent pins 16 of the upper sash 1 are'always locatedin the outer guide 15; and similarly the corresponding pins 16 of thelower sash 2 are always located in the inner guide 14. The lower halvesof said guides are slots so thatsaid lower pins 16 of both sash projectthrough into the sash weight compartments 3 as best shown in Figs. 5, 9,10 and 11, where they eachcarry a metal piece 24 (Fig. 11) looselyrotatable thereon, to which latter in turn the sash cords or chains 25are attached, said cords passing over pulleys 26 (Fig. 11) suspended bylinks 27 from the top of the compartments 3, the other ends of saidcords being attached to the sash weights 28 which, as usual, serve tocounterbalance the weight of the respective sash.

The upper parts of the guides 14 and 15, being the parts shown shaded inFig. 8, have bottoms bridging across between the sides of the guides soas to constitute rooves as shown at 14 in Fig. 4, as distinguished fromthe slots 14 of Fig. 5. The lower portions of the guides must be slotsin my construction in order that the sash weight cords can be fastenedto the lower pins 16 of the sash, whereas the upper portions need notbeslots in my construction but can be grooves whose closed bottomsprevent one from seeing into the. upper portion of the interior of thesash weight compartments.

To keep the sash weights separated and at the same time avoidunnecessarily obstruct- ,sin

ingaccess to the interior parts of the sash inent, located substantiallyparallel to the,

plane of the window opening and projecting from one wall of the-givencompartment between the sash weights therein partially across to thatwall of the compartment containing the guides for the sash.

The retractable upper pins 17 of the sash 1 may be located at willeither in the outer guides 15 along with the lower pins 16 thereof whichis the case when said sash has any of the positions of adjustment shown1n Figs. 1, 2, 3, 4, 11, 15,16, 17 or 20; or said retractable upper pinsof said sashl may be adjusted into the other or inner guides 14 as inFig. 18; or they may be located in neither guide and merely allowed tobear against the adjacent faces of the sash weight compartments 3 as inFig. 19, and in this instance the projecting beads 29 (Figs. 4 and 19etc.) are specially provided for the purpose of forming lateral stopsfor the pins 17, preventing the sash from unintentionally oraccidentally tilting and falling downwardly to a greater angle to thevertical than that shown in said Fig. 19.

Next, referring to the other sash 2, this also can be adjusted intonumerous positions depending upon whether its retractable upper pins 17are adjusted into or out of the guides 14 and 15, and also dependentupon whether the lower pins 16 of said sash are located in the straightupper portion of the inner guides 14, or are in the inclined porarelocated in the same plane. In this in;

stance,.all of the pins of the sash 1 are in the outer'guides 15 as arealso the upper pins 17 of sash 2, but the lower pins 16- of the lattersash are located in the vertical bottom ends 14 of the other or innerguides 14. In this position it is impossible to raise or lower eithersash, norcan either sash be tilted inwardly from the outside of thebuilding. Of course, from the inside, the handles 20 can be operated toretract the upper pins 17 of either or both sash to permit them to betilted, raised and lowered as desired.

Fig. 8 shows still another adjustment of the sash for cleaning theirouter or weather faces from within the room, wherein the downwardly intothe position shown in Fig. 8 to have its weather face cleaned.

When in this position, the sash weights would pull up the outer ends ofthe sash were it not that I provide to prevent this, short lateralbranches 14 and 15 (Figs. 8, 11 and 20) extending upwardly and outwardlyrespectively from the vertical lower portions of the guides 14 and 15adjacent the bottom thereof, into which the sash weights quite naturallypull the lower pins 16 of the sash when they are in the act of beingtilted down as in Fig. 8, whereupon said endslof the sash are preventedfrom being lifted by the sash weights.

lVhen the sash are shut, as in Figs. 3 and 15, I provide means first, tokeep out the weather at the horizontal joint or space between the twosash; second, at the space between the bottom of "the lower sash and theouter sill; and third, at the sides of both sash between same and thesides of the window frame.

Describing these in the order named, I provide a Wide extension '32, ofsubstantially the same width as the sash, from the bottom rail of theupper sash 1, said extension having an inwardly turned lower edge32(Figs. 3 and 8), the latter being receivable into a longitudinallyextending groove 33 (Fig. 8) in the outer face of the top rail of thelower sash when both are shut.

Also, I provide a similar wide extension 34 (Figs. 3 and 8) from thebottom rail of the lower sash 2 with an inwardly turned lower edge 34,the latter being receivable into a longitudinal groove 35 (Fig. 8) inthe outer sill when said sash is shut.

To keep the window weather-tight at the sides, I provide strips 36(Figs. 3', 8, 9 and 10 etc.) projecting from the weather face of eachsash along the side edges thereof, receivable, when the sash are shut,into elongated groove-like inwardly opening but out wardlyclosed/recesses in vertical members 38 secured to the sides'of thewindow frame.

, In short, I have provided by my improvements a. thoroughly practicaltilting-sash windowronstruction, some of the advantages of which are'thefollowing:

(1) Sightly appearance when the sash are shut due to their being in thesame plane.

. (2) The sash when shut cannot lie opened.

from the outside, this feature being contributed to by the fact that thelower pins of the lower sash, when shut, are located in the shortvertical guides 14".

(3) Either or both sash can be adjusted for ventilation, etc., to agreat variety of positions as desired to suit conditions.

(4) The weather faces of the sash can be cleaned from within the room.

(5) 'The sash when closed make a weather-tight window all around, sides,bottom and top. 4

(6) The construction of the sash weight compartments with theirremovable panels permits of ready access to the working parts withinsaid compartments.

What I claim is:

1. In a multiple tilting-sash window-construction, the combination of aplurality of sash having respectively pins at the top and bottomprojecting from their sides, the top pins bein retractable at will; anda window frame wiiose sides are each provided with adjacent inner andouter vertically extending guides for the pins of said sash, the lowerpart of each inner guide inclining downwardly and outwardly andterminating un 'der the lower end of the adjacent I outer guide butwithout communicating therewith. v

2. In a multiple tilting-sash window-construction, the combination of aplurality'of sash having respectively pins at the top and bottomprojecting from their sides, the top pins being retractable at will; anda window frame whose sides are each provided with adjacent inner andouter vertically extending guides for the pins of said sash, the lowerpart of each inner guide inclining downwardly and outwardly andterminating in a short vertical portion extending downwardly from saidinclined part under the lower end of the adjacent outer guide butwithout communicating therewith.

3.-In a multiple tilting-sash windowcom struction, the combination of aplurality of sash having respectively pins at the top and bottomprojecting from their sides, the top pins being retractable at will; awindow frame whose sides 'are each provided with adjacent inner andouter vertically extending guides for the pins of said sash; avertically extendin projectingbead on the side of the window frame atits front edge independent of said guides adapted to' be engaged 'by thetop pins of the sash to prevent unintentional excessive down tiltingthereof.
